Anyway, if any of you folks have information or
samples of old tube based
computing junk (modules, for example, or old unit-record stuff) - could I
bother you to tell me what types of tubes were originally installed? I am
looking for specific numbers, not just "dual triodes".
I have a few IBM plug-in (?logic?gate?) modules.
Module Tubes
AM-5 one tube - 5965(maybe "A") IBM Part# 317261
CF-503 one tube - 5965
PW-505 one tube - 7044 IBM P# 124720
CF-5 one tube - 5965(maybe "A") IBM Part# 317261
TH511 two tubes, both 5696
top one IBM Part# 288626
bottom one IBM Part# 288625
Computer model number unknown
And they all look similar to this:
